There is, of course, a counter argument. The smaller services are not a common target for attacks. Anyone organising a massive DDOS operation is much more likely to target Google or Microsoft than a small operation. In the end, the most important factors are (i) is the organisation technically competent? (Fastmail is); and (ii) are they professional? (Fastmail is not terrible, but could be better).

FM on Twitter just now:

Still down in Aussie.
Dont they have a back up server in another country?

I'm pretty sure their main servers are handled by New York Internet from a New Jersey data center in the United States. https://fastmail.blog/company/nyi-datacentre-move/

It seems this is a new/second outage happening now, beginning about 30mins ago.

Back up in Aust

Back down again?

Down again.

it's back for me

Yep, me too.

It just went down for me. This is getting extremely annoying!

I can’t connect via the app or the web interface here in Baltimore.

Everything Down but Status
 

Pretty much everything down for me -- no Thunderbird, no web, no mobile. Status needs updating.

yep gone again for me. Timing is bad. I'm trying to prepare my Surface Pro for a trip away and I need access to my emails to install some apps.

First world problem but I'll throw something through the TV is the Red Sox lose the MLB today!!!

It's been up and down sporadically for me the past few hours. I'm at my desktop and am glad I have POP setup on my account. When I notice access is temporarily restored, I download the latest batch of emails into Thunderbird, then read at my convenience. Calendar updates locally in TB sync up to FM via CalDAV occasionally.
